Application filed May 26,

To all whom it may concern:

Be it known that we, RIOHARDE. JoNEs, a citizen of the United States,residing at Brooklyn in the county of Kings and State of New York, andTHEODORE P.'A. Von THIEN a citizen of the United States, residing atBrooklyn, in the county of Kings and State of New York, have inventedcertain newand useful Improvements in Stam mg Attachments for (JartonSetting Up l achines, of which the following is a spec1fica-' tion.

This invention relates to mechanism for stamping the date, serial numberor other matter upon cartons.

One object of the invention is to provide convenient meansv for stampingsuch matter upon the carton' during its manufacture without the expenseof any separate opera tion.

Another object is tol aid in accomplishing the above object by utilizingthe forming block of the carton setting-up machine as the anvil againstwhich the carton is pressed during the stamping. I

Another object is to so arrange the mechanism that the bringing about ofeither of the above two objects will also facilitate the settingup ofthe carton by the setting up machine.

Other objects of the invention will appear as the description proceeds;and while herein minute details of the invention are described, theinvention is not limited to these, since many and various changes may bemade without departing from the scope of the invention as claimed.

In the accompanying drawing, showing by way of example one of the manypossible embodiments of the invention,

Figure 1 is a perspective view' show ng the stamping mechanism incombination with parts of the setting-up machine;

Fig. 2 is an inner-end elevation of the stamp and'stamp holder;

Fig. 3 is a side elevat on of the stamp holder; and p Figs. 4:, 5 and 6vare plan, side elevation and inner-end elevation of' a bracket on whichthe stamp operating mechanism is mounted;

This invention is shown in combination with a carton setting&up machinesimilar to S. patent to Scales,

machine comprises an intermittentlyfrota table vertical shaft 1, aspider fast on the Patented July 5, 1921.

upper end thereof and comprising radially disposed revolving arms 2 eachcarrying pending from its outer end a mandrel or former block 6 on whichcard-board cartons are-set up, as fully described in said patent.

The attaching means for the new attachment comprisesa hanger supportingstud v 10 loosely mounted on the upper end of said shaft and providedwith a reduced upper end'll on which is received an opening in theenlargedin'ner end 13 of a radially disposed hanger arm 14 secured'faston said reduced portion by means of a set-screw 15. A rod support 17 issecured on the outer end of said hanger arm and is provided with avertical bore receiving fast therein the upper end of a supporting rod20 having its lower v.end rigidly fixed on some convenient portion ofsaid setting-up machine. I

A stamp holder bracket 21 secured on the upper part of said rod opposite'one mandril position carriesa stamp-holder comprising a horizontalfloor 22 and vertical side flanges 23 each provided with a longitudinalguideslot 24:. A Roberts numbering or dating stamp 25 of universallyknown construction is received in said holder and comprises a frame 27slidable on said floor between said flanges and a stamping inechanism 28slidable in said'frame 27 and to which is secured the outwardlypointingstamp-operating rod 29. Guide-journals 31 are provided on the diate pull-rod-opening A5, and a forwardly projecting beak 46 adapted to engageunder said lug. A1 for limiting the rearward movement of the operatinglever. At the upped end, said lever is providedwith] a flat operatingpart 4:8 adapted to engage a and is stopped by the carton on the block.

knob 47 on the outer end of said operating rod 29. I

As shown in said patent said setting-up machine also comprises anupright rocking lever 82, shown herein comprising a pair of spacedmembers 49 having elbow-parts forming inwardly turned upper ends between which rotatably mounted is a turning roller 50 adapted to turncarton-flaps over the lower end of said forming block 6 during theoperation of the machine. An anchoring rod 52 mounted between said elbowparts carries a grooved collar 58 on which is received the hooked innerend 54 of a pull-rod 55 having its rear portion threaded and passedthrough said pull rod opening and carrying a nut 57, a pair of washers58 between said nut and said operating lever 44, and a compressionspring 60 disposed between said washers.

The operation of the device is as. follows:

The form 6 with a carton thereon moves, during the operation of thesetting-up machine, to the position of Fig; 1, whereupon the rockinglever 82 moves downwardly and inwardly to turn the fiap, as described insaid patent, whereupon the pull rod is drawn inwardly compressing thespring and yieldably forcing the operating lever against the knob, andthe frame inwardly against the action of the springs 83 until it engagesContinued movement of the operating lever and knob causes the stampingmechanism thereof to move inwardly against the action of its ownretracting spring (not shown) until the stamping mechanism is alsostopped by engagement with the carton backed by theformer block 6 as ananvil therefor, thus stamping the impression on the carton.

The yielding action of the compression spring 60 permits still furthermovement of the rocking lever 82 and the roller 50, thereby toform theflap of the carton, the stamp 25 meanwhile exerting to an extent aclamping action on the carton somewhat similar to that exerted by theparts 66, 68 and 194 of Fig. 3 of said patent.

We claim as our invention: 7 1. In combination, a shaft; arms fixed onthe upper end of said shaft; a former block pending from the outer endof each arm; a stub loosely mounted on the upper end of said shaft; ahanger arm having its inner end fast on said stud; a rigidly supportedsupporting-rod having its upper end fast on said arm; a stamp-holderfixed on said rod opposite said block; a stamp thereon; a bracket fixedon said supporting rod below said holder; and operating means carried onsaid bracket for pressing the stamp against a carton on the formerblock.
